Hammer head attachment for wrecking bars



United States Patent HAMMER HEAD ATTACHMENT FOR WRECKING BARS HenryJohnson, Beatrice, Nebr. Application January 24, 1956, Serial No.560,989 1 Claim. (Cl. 25426) This invention relates to hammer headconstruction, the primary object of the invention being to provide ahammer head which may be readily secured on one end of a wrecking bar orsimilar tool providing means whereby one end of said wrecking bar ortool may be used as a claw hammer.

Another object of the invention is to provide a hammer head embodying apair of spaced flanges between which one end of a wrecking bar may bepositioned, and the flanges bent around the wrecking bar in contacttherewith, whereby the meeting edges of the flanges are welded together,holding the hammer against accidental displacement on the wrecking bar.

Still another object of the invention is to provide a hammer head havinga solid portion for use in hammering nails or the like, the claw of thehead extending rearwardly and being so located with respect to the mainportion of the head, as to facilitate the use of the hammer head inremoving nails or the like.

Other and further objects and advantages of the invention will behereinafter described and the novel features thereof defined in theappended claim.

Referring to the drawing:

Fig. 1 is a perspective view of a hammer head constructed in accordancewith the invention.

Fig. 2 is a side elevational view thereof illustrating the hammer headas secured to one end of a wrecking bar.

Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 2.

Referring to the drawing in detail, the hammer head comprises a solidblock of metal indicated generally by the reference character 5 withclaws 6 extending from one edge thereof and at right angles with respectto the forward edge of the block, as clearly shown by Fig. 2 of thedrawing.

Extended from the head at right angles with respect 5 to the claw 6, arespaced parallel flanges 7 that have "ice their outer edges beveled at 8so that when the flanges are bent around a wrecking bar, which in thepresent showing is indicated by the reference character 9, will providea cavity for the reception of welding material indicated at 10, securelywelding the hammer head to the wrecking bar and converting one end ofthe wrecking bar into a hammer.

An enlargement 11 is formed onone surface of the head 5 and provides ahammering surface for hammering nails or the like.

From the foregoing it will be seen that due to the construction shownand described, I have provided a hammer head which is constructed anddesigned for positioning over one end of a wrecking bar where it may besecured by bending flanges on the head into close contact withthewrecking bar and then welding the flanges in position on the wreckingbar to secure them in place.

With this construction, it will be seen that the conven tional wreckingbar may be readily converted for use as a hammer or claw for removingnails or the like.

It might be further stated that due to the fact that the claws 6 extendat right angles with respect to the forward edge of the head, the clawswill not in any way interfere with the use of the device in hammeringnails when the device is to be used as a hammer.

Having thus described the invention, what is claimed is:

A claw hammer structure comprising a rigid bar having a polygonalconfiguration in transverse section and a claw hammer head fixed on saidbar, said head comprising a block, a pair of claws extending rearwardlyfrom said block presenting a flat outer surface parallel to said bar andan inclined inner surface diverging from said bar in a rearwarddirection from. said block, a pair of flanges extending from said blockin parallel relation, said block having a V-shaped recess in the lowerside thereof between said flanges in which the bar is adapted to snuglyfit, each flange being formed of converging portions engaging aboutadjacent, angularly related surfaces on said bar, and welding securingsaid portions together and to said bar.
